Matt Riddle concedes there may not be a room big enough to contain the egos of he and Chael Sonnen, but the American insists he would love a future as "Maximus Deep Waters" in pro wrestling.

Riddle prepares to take on Che Mills at Wembley Arena this weekend, and he was in the mood to entertain at Wednesday's press conference, prompting ESPN to ask if he had met fellow enigma Sonnen before.

"Our egos would clash!" Riddle told ESPN. "He seems like he's nicer in person, we've only spoken once, but when he talks on camera he lets people have it! He's pretty intense."
